Performed 1 system diagnostic on main level unit. Furnace is 29 years old. Coil and condenser is 13 years old. Found failed transformer, not te flood protection, dirty blower wheel, and restricted coil Recommendations refrigerant flow. Unit had high head pressure and was starving at the coil. Due to the age of unit and cost of repairs customer would like to have n estimate for a system replacement. He also wanted a transformer added for a bandaid fix. System is cooling however will not be cooling efficiently when temperatures are rising. The bare minimum basic repairs to get the system running today. Based on our findings today, it might be time to think about getting a brand new system.
